My 307 has recently warned me of this Antipollution fault (and engine management light on) on 2 occasions now. On both occasions, the fault dissapeared after a few starts of the car. Currently the fault isnt appearing. The car didnt lose performance or anything. I couldnt find anything wrong with it. I have booked it in to the dealer.
Is the car still going to have faults logged on its ECU, even if the fault isnt appearing at the moment?
What could cause this?
